If this is also your case, follow this instructable to build a low-fi DJ set: the DIY Turntable as featured on Gizmodo and Engadget, and take the chance to recycle your old cassette player into a new cool instrument.
Step 1: Materials
- Cassette player (better if it's an old one)
- Wire and wire strippers
- Prototyping breadboard
- Soldering iron + solder
- 5 to 9V battery with battery holder
- Some kind of variable resistor or potentiometer
- Arduino with its USB cable
- IRF540 Mosfet (transistor)
- 5 LEDs
- 5 220ohm resistors (brown-red-red)
- one 1kohm resistor (red-black-brown)
- Computer cooling fan
- Box or some kind of enclosure
This project is divided in two parts. By doing only the basics you’ll be able to control the speed of the music without even having to touch an Arduino or write a line of code. Almost zero budget and quite fun.
If you decide to follow to the advanced part, you’ll be able to have the pc fan act as a turntable (although it won’t be real scratching because the gears of the walkman won’t let you play backwards). You'll have total control over the speed of the music and will add whatever effects you like, like the LED indicator.
So, let’s get started!
